— Frank HerbertContext: A man is a fool not to put everything he has, at any given moment, into what he is creating. You're there now doing the thing on paper. You're not killing the goose, you're just producing an egg. So I don't worry about inspiration, or anything like that. It's a matter of just sitting down and working. I have never had the problem of a writing block. I've heard about it. I've felt reluctant to write on some days, for whole weeks, or sometimes even longer. I'd much rather go fishing, for example, or go sharpen pencils, or go swimming, or what not. But, later, coming back and reading what I have produced, I am unable to detect the difference between what came easily and when I had to sit down and say, 'Well, now it's writing time and now I'll write.' There's no difference on paper between the two.

— Frank HerbertContext: No matter how finely you subdivide time and space, each tiny division contains infinity.
But this could imply that you can cut across linear time, open it like a ripe fruit, and see consequential connections. You could be prescient, predict accurately. Predestination and paradox once more.
The flaw must lie in our methods of description, in languages, in social networks of meaning, in moral structures, and in philosophies and religions — all of which convey implicit limits where no limits exist. Paul Muad'Dib, after all, says this time after time throughout Dune.

— Frank HerbertContext: Reevaluation taught me caution. I approached the problem with trepidation. Certainly, by the loosest of our standards there were plenty of visible targets, a plethora of blind fanaticism and guilty opportunism at which to aim painful barbs.
But how did we get this way? What makes a Nixon? What part do the meek play in creating the powerful? If a leader cannot admit mistakes, these mistakes will be hidden. Who says our leaders must be perfect? Where do they learn this?

— Frank HerbertContext: Don't give over all of your critical faculties to people in power, no matter how admirable those people may appear to be. Beneath the hero's facade you will find a human being who makes human mistakes. Enormous problems arise when human mistakes are made on the grand scale available to a superhero. And sometimes you run into another problem.
It is demonstrable that power structures tend to attract people who want power for the sake of power and that a significant proportion of such people are imbalanced — in a word, insane. … Heroes are painful, superheroes are a catastrophe. The mistakes of superheroes involve too many of us in disaster.
It is the systems themselves that I see as dangerous.

— Frank HerbertContext: The current utopian ideal being touted by people as politically diverse (on the surface, but not underneath) as President Richard M. Nixon and Senator Edward M. Kennedy goes as follows — no deeds of passion allowed, no geniuses, no criminals, no imaginative creators of the new. Satisfaction may be gained only in carefully limited social interactions, in living off the great works of the past. There must be limits to any excitement. Drug yourself into a placid "norm." Moderation is the key word…
